1.1 abs 2:
1.123 jmc 3: This file (UPDATING) is intended to be a brief reference to recent
4: changes that might cause problems in the build process, and a guide for
5: what to do if something doesn't work.
1.1 abs 6:
1.123 jmc 7: For a more detailed description of the recommended way to build NetBSD
8: using build.sh, see the BUILDING file.
9:
10: Note that much of the advice in this UPDATING file was written before
11: build.sh existed. Nevertheless, the advice here may be useful for
12: working around specific problems with build.sh.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.166 xtraeme 19: 20071115:
20: The it(4) driver has been renamed to itesio(4) and the old port
21: argument specified in the kernel configuration file is not valid
22: anymore. The itesio(4) driver now uses the Super I/O address port
23: rather than the EC address port. Please update your kernel
1.167 ! wiz 24: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 25:
1.165 jmmv 26: 20071028:
27: The pccons(4) driver has been removed from the NetBSD/shark port.
28: You need to update any custom kernel configuration file you have
29: to remove any references to pccons (which includes removing the
30: now useless XSERVER option) and replace them with the correct
31: entries for the wscons driver. See the GENERIC configuration file
32: for more details.
33:
1.164 gdt 34: 20070913:
35: A latent bug in dhclient/dhcpd that caused it to be unable to
36: enumerate interfaces was fixed. The bug began to cause
37: problems after 20070911 when the kernel's SIOCGIFCONF
38: implementation was repaired. From 20070529 to 20070911 racoon
39: could not enumerate interfaces. (These are noted because
40: normal kernel/userspace version matching hygiene is not
41: sufficient to avoid this problem.) Ensure that both kernel
42: and userland are from after 20070913.
43:
1.163 joerg 44: 20070703:
45: nbinstall has been renamed as it calls the target specific and
46: the logic to pass down STRIP from mk been removed. This forces
47: a re-installation of tools.
48:
1.161 dsl 49: 20070422:
50: The way OS emulations lookup filenames inside the emulation root
51: has been changed. Rather than modify the pathname (and copy back
52: to userspace) namei() and lookup() directly check the emulation
53: root. One side effect is that absolute symlinks inside the emulated
1.167 ! wiz 54: root file system will be relative to that file system - unless they
1.161 dsl 55: start /../ this is useful when the emulated root is a real install
56: that has such links.
57: This might affect symlinks that have been added to reference outside
58: the emulated root.
59:
1.160 jmcneill 60: 20070412:
61: The pckbc driver on sgimips IP32 has been removed. Use macekbc
62: instead. See the GENERIC32_IP3x kernel configuration for an
63: example.
64:
1.159 gdt 65: 20070319:
66: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
67: on many platforms due to incorrect flags settings. If you
68: updated and built after about 20070315, do "nbmake-$arch
69: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
70: rebuild of object files that might have been built
71: incorrectly, and ensure that you have at least
72: src/lib/libc/Makefile 1.130.
73:
1.158 dbj 74: 20070210:
75: src/sys/sys/{sa.h,savar.h} were removed.
76: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
77: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
78: will allow dependencies on those files to get get rebuilt
79:
1.157 apb 80: 20070209:
81: The threading model was changed when the newlock2 branch
82: was merged to NetBSD-current. If you boot with a new
83: kernel (version 4.99.10), then you also need a new pthread
84: library (/usr/lib/libpthread.so.0.7). If you boot with
85: an old kernel, then you need the old pthread library
86: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
87: the pthread library in sync, old threaded applications should
88: continue to work with an old or new kernel. Note that named(8)
89: is the only threaded application in the base system.
90:
1.154 he 91: 20061214:
92: Following the move of string_to_flags() and flags_to_string()
93: from the bin/ls/ sources to libutil, users doing UPDATE builds
94: will need to do a "make cleandir" in
95: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
96: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 97: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
98: as the installation images in distrib/
1.154 he 99: in order to excise stale references to the old stat_flags.h header
100: file in the ls sources -- stat_flags.h has been removed.
101:
1.152 christos 102: 20061108:
103: The configure script used in the src/tools/gcc compiler has been
104: changed to indicate that our libc has ssp support built-in and
105: does not depend on -lssp and -lssp-nonshared. You'll need to
106: make clean in src/tools/gcc first to rebuild the compiler.
107:
1.151 rpaulo 108: 20061009:
109: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
110: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
111:
1.150 bjh21 112: 20060814:
113: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
114: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
115: kernel configuration for an example. X servers from the last
116: few years should cope.
117:
1.149 christos 118: 20060703:
119: MPACPI is no more. We always configure PCI interrupts using ACPI
120: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
121: to ACPI_SCANPCI. Thanks to work from fvdl.
122:
1.148 dogcow 123: 20060627:
124: socket(2) has changed, and its system call has been versioned.
125: For userlands with the old version of socket(2), make sure that
126: your kernel has 'options COMPAT_30' set, or else 'bad system call'
127: errors will result.
128:
1.1 abs 129: Hints for a more successful build:
130: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 131: Use build.sh, but do not use its "expert mode":
1.132 jmmv 132: This will automatically build the tools in the
1.123 jmc 133: correct order, and it will keep the tools and the
134: new build products from interfering with the running
135: system. This will allow you to ignore most of the
136: other advice in this file.
1.2 mrg 137: Build a new kernel first:
138: This makes sure that any new system calls or features
139: expected by the new userland will be present. This
140: helps to avoid critical errors when upgrading.
1.1 abs 141: Use object directories:
142: This helps to keep stale object
143: files from polluting the build if a Makefile "forgets"
144: about one. It also makes it easier to clean up after
145: a build. It's also necessary if you want to use the
146: same source tree for multiple machines.
1.123 jmc 147: To use object directories with build.sh:
148: a) invoke build.sh with the "-M" or "-O" options.
149: To use object directories without using build.sh:
1.1 abs 150: a) cd /usr/src ; make cleandir
1.2 mrg 151: b) Add "OBJMACHINE=yes" to /etc/mk.conf
152: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 153: d) cd /usr/src ; make build
1.2 mrg 154: Note that running "make obj" in a directory will create
155: in obj.$MACHINE directory.
1.1 abs 156: Build to a DESTDIR:
1.123 jmc 157: This helps to keep old installed files (especially libraries)
158: from interfering with the new build.
159: To build to a DESTDIR with build.sh, use the "-D" option.
160: To build to a DESTDIR without using build.sh, set the DESTDIR
161: environment variable before running make build. It should be
162: set to the pathname of an initially empty directory.
163: Problems: if you do not use build.sh, you might need to
164: update critical utilities without using DESTDIR since
165: nothing is executed from what is installed in DESTDIR.
166: (See critical utils, below.)
1.1 abs 167: Build often:
168: This keeps critical utilities current enough to not choke
169: on any other part of the source tree that depends on up to
1.123 jmc 170: date functionality. If you use build.sh, you should not have
171: this problem.
1.1 abs 172:
173: What to do if things don't work:
174: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
175: When things don't work there is usually a few things that commonly
176: should be done.
177: 1) make includes
178: This should be done automatically by make build.
179: 2) cd share/mk && make install
180: Again, automatically done by make build.
181:
182: Failsafe rebuild of a small part of the tree:
183: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
184: To make sure you rebuild something correctly you want to do
185: something like the following:
186: 1) Make sure the includes and .mk files are up to date.
187: 2) Make sure any program used to build the particular
188: utility is up to date. (yacc, lex, etc...)
189: 3) cd ...path/to/util...
190: make cleandir
191: rm ...all obj directories...
192: make cleandir # yes, again
193: make obj
194: make depend && make
195:
196: Failsafe rebuild of the entire tree:
197: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
198: If you really want to make sure the source tree is clean and
1.2 mrg 199: ready for a build try the following. Note that sourcing /etc/mk.conf
200: (a make(1) Makefile) in this manner is not right, and will not work
201: for anyone who uses any make(1) features in /etc/mk.conf.
